No biscuit!}; } } That works okay, but the code could certainly be more readable. In its simplest usage, this module makes that code more readable by providing three subroutines--'LIST()', 'SCALAR()', 'VOID()'--that are true only when the current subroutine is called in the corresponding context: use Contextual::Return; sub get_server_status { my ($server_ID) = @_; # Acquire server data somehow... my %server_data = _ascertain_server_status($server_ID); # Return different components of that data # depending on call context... if (LIST) { return @server_data{ qw(name uptime load users) } } if (SCALAR) { return $server_data{load} } if (VOID) { print "$server_data{load}\n" } else { croak q{Bad context! No biscuit!} } } %prep %setup -q -n %{cpan_name}-%{version} %build %{__perl} Build.PL installdirs=vendor ./Build build flags=%{?_smp_mflags} %check ./Build test %install ./Build install destdir=%{buildroot} create_packlist=0 %perl_gen_filelist %clean %{__rm} -rf %{buildroot} %files -f %{name}.files %defattr(-,root,root,755) %doc Changes README %changelog ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Remember to have fun... -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
